Non-A, non-B hepatitis: a case report.
Ultrastructural changes in a liver biopsy obtained for diagnostic purposes from a patient with suspected non-A, non-B hepatitis were consistent with hepatitis and included dilatation and disaggregation of the endoplasmic reticulum, hepatocyte disarray, and variations in mitochondrial size. In addition, some foci of hepatocytes showed atypical cytoplasmic changes including intranuclear cytoplasmic pseudo-inclusions, consisting basically of invaginations of the cytoplasmic mass into the nucleus, glycogen deposits in the same nuclei, and frequently accumulations of fat droplets. The mitochondria were generally pleomorphic, and occasionally the mitochondrial cristae were arranged longitudinally. Dilatation, hypertrophy, and distortion of the Golgi complexes were found in affected hepatocytes. Similar ultrastructural changes have previously been reported in human hepatocellular carcinoma as well as in carcinomas of other tissues.
